[PATCH] libsanitizer: don't enable for MIPS Linux without GNU libc [PR 106136]

[Xi Ruoyao via Gcc-patches]

In libsanitizer code, the size of some GNU libc data structure (notably,
struct stat) is hard coded.  These sizes may trigger a static assert
buidling against another libc.

Just make non-GNU libc targets UNSUPPORTED now.  If someone really cares
about those alternative libc implementations, please submit patch to
LLVM project adding the support.

        * configure.tgt: Change mips*-*-linux* to mips*-*-linux-gnu*
        because it fails to build with non-GNU libc.
